to accommodate the ratchet dog 16 the wall of the bore 14 is provided with a semi-cylindrical seat 17 (to receive the pivoted rounded end 18 of the dog) and with a plane faced notch 19 to accommodate the movements of the ratcheting m I which are completely and permanently assembled in co-operating relationship without the employment of screws, rivets or the like.

A coordinate object is to so form the wrench that it will be completed in its assembled form and its component parts secured in posit-ion by a single compressing operation.

, In the accompanying drawing illustrating a preferred embodiment of our invention,

Fig. 1 is a side elevational view of the larger end of a drop forging constituting one of the elements of our improved tool; r

Fig. 2 is a section taken on the line 2-2 of Fig. 1 and looking in the direction indicated by the arrows;

Fig. 3 separately illustrates in side elevation the several elements which are intended. to be assembled with the aforesaid forging in the manufacture of our improved ratchet wrench;

Fig. 4 is a view similar to Fig. l but showing the socket-ratchet, its dog and cooperating spring, and one of the wrench side plates applied to the head of the handle forging;

Fig. 5 is a view partly in section and. partlyin elevation, illustrating how the flanges of the forging head are caused to cooperate with the side plates to hold the several elements of the wrench in cooperating relationship without the use of rivets, screws or the like; and

Fig. 6 is a view in perspective of the completed Wrench. i

Similar characters of reference refer to similar part's throughout-the several views. O'ur improvedwrench includes an integral drop forging having a handle part 7 and the head 8.

On its side faces the, forging head 8 is provided with symmetrical contiguous flanges 99 which j border and project outwardly substantial distances from the parallel side plate seats 1010. The inner surfaces 11 of the flanges 99 flare slightly away from their respective seats 10-40, vsaid inner surfaces 1l11 of the flanges being arranged snugly to embrace the side plates 12-12 when the latter are assembled on their respective which preferably extends entirely through the end of the dog.

The side plates 12l2 are provided with circular apertures 20-20 adapted to receive and journal the cylindrical extremities 212l of the socket-ratchet member 15. The said socketratchet element is also provided on its outer surface, intermediate its cylindrical extremities with the square or other polygonal socket 23,

have been completely and permanently assembled in the manner presently to be described.

The assembly of the several parts of the wrench is effected as illustrated in Figs. 4 and 5,'the

socket-ratchet element 15 occupying the forging head bore 13, the dog 16 occupying the forgin'g bore 14 (and particularly the seat 17 and notch 19 thereof), the dog spring 16--a being confined between the dog and that portion of the bore 14 whereof the dog 16 is a chord, and the side plates 1212 lying within the flanges 9-9,,resting on seats 1010, and serving to journal the cylindrical extremities 21-21 of the socket-ratchet element 15. a l. With the several parts of the wrench'assembled as just described, and as illustrated in Figs. 4 and 5, the wrench head is inserted between? and operated upon by opposed female'dies 25-25,

respective seats 1010 without any necessity for the employment of rivets, screws or the like to accomplish such purpose (see Fig. '5).

The dog 16 and its.spring16a cooperate with the teeth 2222 of the socket-ratchet member in a well known manner.

Having thus illustrated and described a preferred embodiment of our invention, as well as the preferred manner of producing the same,

what we claim is new and desire to secure by Letters Patent of the United States is:

1. A ratchet wrench comprising a handle member having an opening extending through it at the end thereof for the reception of a socketratchet member, a pawl and a spring bearing thereagainst, flanges on each side of the handle member extending in opposite directions and circumscribing said opening, seats occupying parallel planes within the confines of the respective flanges and extending between said opening and the bases of said flanges, side plates resting,

article overhanging and contacting the outer margins of said side plates firmly and permanently to retain the several parts of the wrench in assembled relation.

2. A ratchet wrench comprising a handle member having an opening extending through it at the end thereof for the reception of a socketratchet member, a pawl and a spring bearing thereagainst, flanges on each side of the handle member extending in opposite directions and located adjacent to said opening, seats occupying parallel planes within the confines of the respective flanges and extending between said opening and the bases of said flanges, side plates resting against said seats and lying within the embrace of said flanges, said flanges projecting sufficiently to engage and secure said side plates, a socketratchet occupying said opening and confined therein by said side plates for coaction with said vpawl, said socket ratchet having cylindrical extremities, said side plates having opposed, aligned circular apertures which receive and constitute bearingsfor the cylindrical extremities of the socket-ratchet member, the outer parts of said flanges in the finished article engaging the outer edges of. said side plates firmly and permanently to retain the several parts of the wrench in assembled relation. a

3. A ratchet wrench comprising a drop forging formed with a handle portion and with an enlarged head portion, said head portion having an opening extending through the head portion at one end of said ratchet wrench for the reception of a socket-ratchet member, a pawl and a spring bearing against saidpawl, said head 'portion having laterally projecting flanges on each side of the head portion extending in op- ,posite directions and spaced from said opening but located adjacent thereto, said head portion having an oppositely located seat on each side, said seats being in parallel planes and extending between said opening and the bases of said flanges, said flanges projecting outside of said ratchet located in said opening and confined by ,1;

said side plates for co-action with said pawl, said socket-ratchet having cylindrical extremities forming trunnions for said socket-ratchet, and said side plates having opposed aligned circular apertures receiving and forming bearings for the cylindrical extremities of the socketratchet member, and integral parts of said flanges in the finished article overhanging and contacting parts of said side plates firmly and permanently to secure the side plates against said seats, and to retain the several parts of the wrench in assembled relation.

4.
